摘要 复杂网络的分形特性被誉为复杂网络的第三大基本拓扑特性,对这一特性的研究有助于深入理解网络结构的复杂性。信息维数法是度量复杂网络分形特性的常用方法。然而,现有的信息维数法主要用于分析无权网络的分形特性,对加权网络分形特性的分析并不完全适用。受加权网络盒维数算法思想的启发,提出了一种基于信息维数的加权网络分形特性分析方法。首先,利用该方法分析了一类具有规则分形结构的谢尔宾斯基加权分形网络, 结果表明该方法计算所得的信息维数值与该网络的理论维数值十分接近。然后,利用该方法分析了三个实际加权网络的分形特性,并将分析结果与利用加权网络盒维数算法所得结果进行比较,结果表明该方法同样能够较好地度量实际加权网络的分形特性。

Abstract:The fractal property is considered as the third fundamental topology features of complex networks. Studies on the fractal property of complex networks are of great significance for understanding the structure complexity of the network. The information dimension method is a useful tool to measure the fractal property of complex networks. The existing information dimension method is mainly used to analyze the fractal property of unweighted networks, and it is not fully applicable to analyze the fractal property of weighted networks. In this paper, motivated by the idea of box-covering algorithm for weighted complex networks, a fractal analysis method of weighted networks based on information dimension is proposed. We first apply this method to study the fractal property of a family of constructed “Sierpinski” weighted fractal networks, the results show that the fractal dimension of these networks obtained by the proposed method are very close to its theoretical similarity dimension. Then, we apply the proposed method to study the fractal property of three real-world weighted networks and make a detail comparison with the box-covering algorithm, results demonstrate that the proposed method is effective for the fractal scaling analysis of real-world weighted complex networks.
